| 摘 要： | 反应堆内的快中子与一回路冷却剂水中的16O发生俘获反应会产生放射性核素16N。16N是压水堆核电厂核岛系统设计中需要重点考虑的辐射源项。文章在分析了大亚湾和台山核电站16N源项计算不足的基础上,提出一套精确计算堆芯多群中子通量和细致模拟冷却剂在堆内外流动过程的计算方法,保障了相关核岛系统设计和设备间屏蔽设计的正确性。

| Abstract: | Abstract： The radioactive nuclide U＇N is genemtevl by capture reaction of ~60 and fast neutron inside the reactor primary coolant water. 16N is an important source term to be considered in nuclear island system desire for PWR. To protect the correctness of nuclear island system design and shielding design tmtween equipment, this paper presents a more accurate and reasonable method to analyze the mN source term, which is bas~ on revising and in＇lproving the calculation of ~6N given in the Daya Bay NPP and Taishan NPP design. |
